MAPLAD18KP200AE3 is a transient voltage suppressor diode (TVS-Diode) manufactured by Maruwa. It has the general outline of an electrolytic capacitor, sporting common anode and cathode pins. This component is most commonly used in the protection of electronic circuitry from the effects of ESD (electrostatic discharge) and other voltage transient events.When subjected to an electrical transient event, the diode shortens the length of the transient, thus preventing damage to the surrounding circuitry. The MAPLAD18KP200AE3 has a VBR rating of 2000W (Volts Breakdown/ Reverse Stand-Off Voltage), and an ID (long term operating diode current) of 8A (Amperes).It also features a VBR Rating of 2000W and an avalanche current rating of 400A, helping it protect systems from high-frequency and low-energy transients. Additionally, its CDF (Common Mode differential impedance) rating stands at 600 Ohms, which allows the diode to withstand different types of electrical disturbances.When not subjected to a transient event, the diode works as an open circuit, not passing any current. When subjected to an event, however, the diode becomes a short circuit and conducts current. This allows it to dissipate both energy and ripple current (which threaten the life of the device) by rapidly recovering to its open circuit state after the voltage decreases.To further aid in protection against overvoltage, the MAPLAD18KP200AE3 also features an inicial energy boost of approximately 20-45V; this helps reduce a brief increase in voltage during short duration events. In addition, its capacitance and self-healing properties allow it to perform with lower degradation over time.The MAPLAD18KP200AE3 is typically meant to be used on equipment such as PC motherboards, mobile phones, tablets, etc. where a high level of protection is necessary from electrical disturbances. Furthermore, it is suitable for a wide range of applications, including automotive and industrial fields, where voltage transients are more common.It’s worth mentioning that the MAPLAD18KP200AE3 should only be used after detailed testing for proper operation in specific applications; this should include the verification of the breakdown voltage, capacitance, and current ratings of the part.In summary, the MAPLAD18KP200AE3 is a transient voltage suppressor diode primarily designed for use in the protection of electronic circuitry from the effects of ESD and other voltage transient events. It is notable for its VBR rating of 2000W, avalanche current rating of 400A, and CDF rating of 600 Ohms; its inicial energy boost of approximately 20-45V further aids in the protection against overvoltage. It is suitable for a wide range of applications, but it should only be used after detailed testing for proper operation.
